The invention relates to desk copy-holders to be used in connection Vwith typewritlng machines, and its 'main object is to provide a copy-holder which will be compact, simple 5 and eflicient. Y

Thecopy-holder is and of neat appearancer in both operative and folded conditions.

A flat and light work-table is hinfged at 10 its lower or-'front edge to the front o a flat base, the angle of the table being regulatable to suit the operators line of vision by shifting a crutch or support into selected notches rovided in rearwardly-projecting side This crutch or support is made of a U-shaped piece of heavy wire having its end outwardly bent and pivotally mounted at the rear of said base.

Anotherv feature is a yieldable clip for the work near the top ofthe table. This cllp is a heavy wire, which bends down through a hole in the table and has a long stem extending down along the under side of the table; the lower end of the stem being fastened to the table and the stem being sufciently long to make it limber, so that it may serve as a spring which normally holds the work-cli yieldingly pressed against the table. aid stem is suificiently spaced from 3p the under side of the table to permit the releasing of the clip by merely pressing up its ing to Figure 3.

free end toward the under side of the table.

To fasten the lower end of the stem to the work-table a knuckle is formed by rolling up a stamped-out portion of 'one of the side Hanges of the table, and said lower end is bent up through said knuckle and then bent at rightangles across the under side of the trble so as to form the fulcrum of the spring c 1 nother feature of the invention is that the stem of said yieldable clip extends under p onevof the flanged side edges of the table and `parallel therewith over substantially the en- 4tire height of the table, so that it may serve as a lateral guide for the usual lie-nden Still another feature of the invention is that the line-finder is mounted with frictional engagement to slide up and down along the stem, means being provided for insuring pliant or collapsible,

said frictional engagement against acc-idental displacement, while permittin said sliding movement when the line-iin er is manually raised or lowered along said stem.

A further feature ofthe invention is to provide the front end of the fla-t base with an upturned flange, serving as a support for the hinge 'of the work-table and as arreinforcing rib of the base, and with a pair of lateral upturned ears co-operating with the side flanges of the work-table to hold said latter centered onsaid base, while the rear end thereof is also provided with an -upturned ange, acting as a reinforcing rib, and with two lateral upturned ears, serving as bearings for the pivot-ends of the crutch. Other features and advantages will heref inafter appearf In the accompanying drawing,-

Figure 1 is a perspective-view of a cop 70 holder, shown in operative position, and embodying the present invention. y

- Figure 2 is a side elevation, showing the copy-holder collapsed 'or folded for packing or carrying purposes, with parts broken away for clearness.

Figure 3 is a fragmentary sectional view of the line-finder head, and shows how the 'line-finder is frictionally mounted on the stem of the work-clip;

Figure 4 is a perspective view correspond'- In the embodiment of the invention shown in the drawing, the desk copy-holder comprises essentially a work-table 10 hinged to S5 the front edge of a base 11 and a U-shaped crutch or support 12 hinged to the rear edge of said base and co-operating with three pairs of notches 13 provided along two rearwardlyproiecting side flanges 14 of the work-table. 90 he pliant or collapsible triple structure thus obtained forms,.when folded (Figure 2), a compact flat box of neat and attractive appearance, while the work-table may be readily inclined in three different slant positions and held fast in the selected position by engaging the free end of the crutch 12 in either pair of notches 13. A work-sheet 15 or a note-book may be held fast on the table 10 bymeans of a yield- 10 able or s ring clip 16, arranged near the top of the ta le parallel with the top edge thereof. r1`his clip is a heavy wire, which bends down through a hole 17,`provided in the table, 5 and has a long stem 18 bent at right angles down along the under side of the table. The lower end of said stem 18 is bent up through a knuckle 19, formedwith a part of the lefthand side flange 14 by stamping out two clearances 20, and the stem is then bent at right angles so as to form` a projection 21 extending across the underside of the table and through a hole 36 of the right-hand flange 14, and acting as the fulcrum of the 15 spring clip 16.

The stem 18 is sufficiently spaced from the under side of the table 10 to permit the releasing of the spring clip 16 by merely pressing up the free end of said stem toward the 20 under side of the table. A rlhe lower or front edge of the table is upturned so as to form a ledge or rest 22,

Y against which may rest the vlower edge of a note-book. The center portion of said flange a5 14 is stamped out on both sides at 23, and is rolled, so as to form a hinge-knuckle 24. rllhe top or rear edge of the table is turned downwardly, so as to form a reinforcing flange or rib 25.*'

The fiat base 11 is likewise provided at both ends with upturned flanges 26, 27 acting as reinforcing ribs.

The flange 26 presents two rolled-up eX- tensions 28, forming the lateral knuckles of the table hinge. A pintle 29 connects the aligned knuckles 24 and 28.

This flat base 11 presents furthermore a rear pair f upturned side ears 30, serving as bearings for the outwardly-bent pivotends 31 of the crutch 12. l

A swaged or extruded lug 32 is stamped out of each of said pivot-ends, so as to serve as a stop or abutment, yieldingly held pressed against said ears by the mere elasticity of the crutch 12, in order to prevent any side shifting of said crutch, and to center it with respect to the work-table 10.

ln order to increase the elasticity of the side arms of the crutch v12 and to reinforce said latter, double folds 33 ends of a cross-piece 34 of the crutch 12.

The fiat base 11 is also provided at its front end with a pair of upturned side ears 35 which co-operate with the side ianges 14 of the work-table to center said latter with respect to the base 11, and prevent anv side shift of said table.

At the point where the clip-stem 18 is secured into the curled portion or knuckle 19 of the side flange 14, it will be noted that said stem extends downwardly for a short distance in a plane parallel with and adjacent to said flange, and then extends in this same plane parallel with said flange over substan- 65 tially the entire height of the table. This is Y ably holding the are formed at both done for two reasons, a sufficient elasticity of the stem 18 for reliwork-sheet 15 fast in positi on by means of the cli 16, and a suflicient play or releasestroke o said latter for allowing the clamping of-note-books of variable thickness, and, second, so that said stem 18 may be used as a lateral guide for the sliding head 37 ofthe usual line-finder 38.

Said head 37 is mounted with frictional engagement to slide up and down along said stem 18 by means of a clamp, one jaw of which is formed by a channeled edge 39 of the head'37, while the opposite i,aw is formed by a similarly channeled clamping piece 40.

A flat spring 41 with a channeled free end 42 is pressed in said clamp by means of bolts 43 and nuts 44 (Figure 3). A clearance 45 is provided in the portion play to the channeled edge 42 of said spring, which presses against the stem 18 opposite the channeled edge 39, so as to reliably retain the line-finder 38 in its adjusted position, though permitting it to be slid with ease along thestem 18, when desired.

-Variations may be resorted to within the scope of the invention, and portions of the improvements may be used withoutbthers.
